A well-maintained heat pump means clean air, energy savings, a better appliance service-life, and optimal performance.

But what should you check and inspect? Can you do part of the maintenance yourself? What does a professional inspect during maintenance?

What you can do

Always consult your operation manual to know how to handle your heat pump, see what maintenance you can do yourself and how to do it. The required maintenance may vary according to your system. The first step is usually to power off the system. A few times a year, rinse off the air filters and reinstall them once they have dried. Make sure your heat pump’s outside cover is not obstructed. Remove anything that might have gotten stuck.

Professional maintenance

Some heat pumps require maintenance once a year, while others might need it once every three years. These maintenance sessions allow you to make sure that your appliance is running smoothly, and they ensure its best performance.

Wall-mounted system

The technical expert doing maintenance on your wall-mounted heat pump checks the compressor, the refrigeration circuit, the controls, the air filters, and the drainage system. For the compressor, the technician checks and adjusts the coolant level, check the outside sound level, the refrigeration pipes’ insulation, the electrical and mechanical connections, as well as anchoring and support. He then checks the controls, such as the remote and the electrical connections, and he makes sure the selectors are running smoothly, adjusting them if necessary. Lastly, he cleans the air filters and checks the drainage pipes.

Central system

During your central heat pump’s maintenance, the technical expert checks the compressor, the condenser, the interior fan, and the coil. For the compressor, the technician checks the electrical connections, the sound level, and vibrations. He makes sure the safety valve is airtight, the crankcase and four-way valve are running smoothly, and adjusts the coolant level when needed. On the air-cooled condenser, he lubricates the motors, makes sure the propeller, anchoring and support are in undamaged shape, and cleans the coil if necessary. Lastly, for the interior fan, he lubricates the motor, makes sure the hinges are in undamaged shape, and ensures that the fan is well-balanced. He also inspects the fresh air dampers and makes sure they are airtight.

Cleaning the pipes

Once every five years, the pipes should be cleaned to remove any dust, bacteria and mould that could potentially grow. However, if you suffer from allergies or respiratory disease, have any long-haired animals, have recently renovated, or live with someone who smokes, it is recommended getting them cleaned more often.

Comfort and performance

By regularly doing maintenance on your heat pump, you are ensuring your best comfort and health, and making sure your system provides optimal performance for many years to come.
